Test whether Windows can reach the Wi‑Fi router, then check for a proxy, VPN, or security filter—these are the most useful remaining checks because the PC fails on multiple networks and resets and driver reinstalls have already failed.
1. Test the connection to the router
This is a diagnostic command, not another network reset:
- Right-click Start and select Terminal (Admin).
- Run:
ipconfig
- Under Wireless LAN adapter Wi-Fi, find Default Gateway.
- Ping that address. For example:
ping [IP Address]
Microsoft uses this test to determine whether the PC can communicate with the Wi‑Fi router ^1^.
Interpret the result:
- Four replies: Wi‑Fi communication with the router works. Continue with the proxy/VPN checks below.
- “Request timed out” or “Destination host unreachable”: Windows is associated with Wi‑Fi but cannot communicate properly with the router. Record the output and generate the wireless report in step 3.
- No Default Gateway: The PC did not obtain a usable network configuration. Because this happens on different networks and network reset already failed, collect the report before making further changes.
2. Remove traffic-blocking software from the path
A configured proxy, VPN, firewall, or security product can prevent browsing even while Windows reports Wi‑Fi as connected ^2^.
- Open Settings → Network & internet → Proxy.
- Under Manual proxy setup, turn Use a proxy server off unless it is required by work or school.
- Leave Automatically detect settings enabled.
- Open Settings → Network & internet → VPN and disconnect any active VPN.
- Fully exit any third-party VPN, web-filtering, or antivirus network-protection application, then test a browser again.
If this is a managed work or school PC, do not remove an organization-required proxy or security product; contact its administrator instead.
For third-party antivirus, temporarily disable only its web/network protection long enough to test one site, then re-enable it immediately. If access returns, repair or remove that product rather than leaving protection disabled.
3. Generate the Windows wireless report
- Open Terminal (Admin).
- Run:
netsh wlan show wlanreport
- Open the HTML file path shown in the command output.
- Review:
- Red error circles in the Wi‑Fi summary chart
- The affected connection session
- Network adapters → Problem number
- Driver version and date
- Disconnect reasons and script output
The report contains Wi‑Fi events from the previous three days, connection sessions, adapter details, and any adapter problem number ^3^.
4. Choose the next action from the results
- Gateway replies, but browsers still fail: Concentrate on proxy, VPN, antivirus/firewall, or browser filtering rather than reinstalling the Intel adapter again.
- Gateway does not reply on every tested network: Use the report’s Problem number or connection error to identify the next repair. If a problem number appears, provide it along with the Intel adapter model.
- The problem began directly after a Windows update: Open Settings → Windows Update → Update history → Uninstall updates and check whether the latest update can be removed. Do this only when the timing clearly matches.
- No useful error appears and every network still fails: Run the Windows 11 troubleshooter through Start → Get Help, search for network troubleshooter, and save its result. Microsoft identifies Get Help as the Windows 11 automated network diagnostic ^1^.
Avoid another factory reset until the gateway result and wireless report have been captured; otherwise, the most useful failure details may be lost.
